DENTON, Texas (February 20, 2009) – Peterbilt Motors Company today introduced a new proprietary Fuel Efficiency Package designed to provide fuel savings gains of up to 12 percent for its traditionally styled Models 388 and 389. 

The Fuel Efficiency Package utilizes a set of proprietary components to reduce vehicle drag by up to 24 percent, resulting in an estimated $5,600 in savings annually (130,000, $2.30/gal) versus a comparable non-equipped Peterbilt Model 388 or 389. Benefits were validated by the company with state-of-the-art technologies such as computational fluid dynamics studies, wind tunnel testing and on-track drag metering.

“Reducing fuel consumption and overall operating costs are primary concerns for all customers; the new Fuel Efficiency Package provides tangible savings that help our customers compete in today’s challenging economic environment,” said Bill Jackson, Peterbilt General Manager and PACCAR Vice President.  “For fleets and owner-operators who prefer Peterbilt’s traditional styling, the Fuel Efficiency Package offers fuel savings with uncompromised style and performance.”

Package components include aerodynamic mirrors, sleeper extender, roof fairing and trim tabs, composite sunvisor and a sleeper roof transition. Components redirect airflow and provide less drag resistance resulting in improved overall fuel economy and a more streamlined appearance.  The Fuel Efficiency Package complements the standard features engineered into the Models 388 and 389 such as the redesigned hoods, headlamps, hood ornament and crown and grille. The Fuel Efficiency Package will also be available from PACCAR Parts for the Models 388 and 389, as well as earlier traditional Models 378 and 379.
